s claims. (c1. 12o-sz) The invention relates to copy holders andmore Il hinged, as at Il, to the casing I but adapted particularly to an improved type of copy holder made so that it exposes only a predetermined amount of the copy held by it. s v'Ehe general object ot this invention is to present an improved, inexpensive and easily oper- -ated copy holder which overcomes objections common to those of the present type.

one object of the invention is to provide a lo 'copy holder which is so constructed that the copy held in it is exposed and advanced one or more lines at a time.

Another object oi' the invention is to provide means for conveniently advancing the copy in it the copy holder one or more lines at a time by rote control.

in ma. e with the patent statutes one Ibest known iorm of the invention is illustrated in the accomp t rf t drawings wherein: no Fie i is an elevation oi one embent oi invention, showing it in combination with a sdard y:

ie to Figure' l oi the drawings, which as trates an application of the invention, the

letter T indicates a typewriter mounted on a desi: D having a copy holder C' associated therewith which incorporates lthe principles of the invention. The copy holder C includes a sheet n so metal casing it mounted on a bese ii so that the can can be ndi to the most convenient position by theI typist. Preferably, this is accomplished by forming the hase it with a vertical bore receiving a post it which is pivotaily secured 4s to a bracket it on the cs. Thumb nuts It and it in the base it and on the bracket I8,

resneetively` hold the mounting means in their,

adjusted ,tions The casing it, substantially oval shape'in 50 c-section. has a longitudinahopeningiiin its top ace and a rectangular aperture 22 in the lower half of its iront surface, both of f which extend the lensth of the casing I0. Sidewalls 2l and 24 close Vthe end oi the casing 55 Il. The aperture 22 is normally closed by a door to be swung open in the direction of the arrows in casing.

Within the casing it and directly behind the aperture 2z is a rubber roll 26 mounted on a shaft 2l. .iournalled in and extending through the side-walls 23 and 24. The rubber roll 28 serves as supporting means for copy in the copy holder C. The end of the shaft 2l extending 1o through the side-wall 23 has a circular knob 2S secured to it so that the roll 26 can be manually rotated if desired.

Guide arms all are provided to guide the copy inserted through the aperture 2i onto the roll 15 2t and from it back to and out of the aperture 2i. The arms 3@ are mounted on the anges of a channel member tiy which is secured to the inside oi the side-walls it and 2i, immediately below the aperture 2l l by brackets di. To aid 20 the arms it in guiding copy onto the roll 2t, and to center and straighten said copy. a guide plate i3d is suspended from the rear edgeof thel casing id. Positioned on the guide iid is a metal plate dit having a perpendicular side flange which functions to true up one edge of the copy paper so that the paper enters the roll 2t perpendicular to it and at the desired place as the plate it can be moved longitudinally on the guide 38 and xed in any desired position by a set screw 42 30 which bears on the casing il).

In order to secure positive motion between the roll it and the copy paper around it, small rollers v tt are mounted to bear resiliently but releasably upon the roll it. Preferably the rollers 3i are 35 rotatably supported by arms lit uniformly spaced valone` the roll 2t and rigidly attached to a shaft tt which is journalled in the side-walls 2t and it and extends through the side-wall 23. The shaft is mounted behind the roll 2t in such 40 a manner that the copy paper guided to the roll it by the arms t@ and the plate ddgoes hetweenvv the arms til, which are arcuate in shape that they may ilt closely to the surface of the roll 2t. This makes the copy paper go between the rollers 45 33 and the roll 26 so that the pressure of the rollers it on the roll 26 binds the copy paper to the roll 2t and insures positive movement of the paper. l

The end of the shaft 35 extending through the 50 side-wall 23 has a lever arm 3l ilxed to it. When the arm 3l is pushed down it rotates the shaft 35 through an arc, thereby moving the arms 34 and the rollers 33 away from the surface of the roll 26. This removes the pressure holding the 2` j copy paper to the roll ,29fand permits'straigh ing or movement of the copy paper without mov- The door II otlthe casing I9 is formed with a relatively narrow rectangular apertureA I9 which exposes portions ofthe copy mounted by the roll 29 so that it can be read from the front oi! the copy holder C. The. distance between lines on the copy may vary and the aperture I9 may expose more than one line at a time. A cover 44 is slidably mounted on the door II to vary the opening of the aperture i9, so as to expose but one line oi' copy through'the aperture i9.

A cover 44 is provided the position of which, relative to the aperture T9, is preferably controlled by means of rods 49 which are pivotally attached to one end of the bell cranks 41. The bell cranks 41 are pivotally mounted at 49 on the door II and their other ends are attached to the cover 44 at 49. The ends of the rods 49, not attached to the bell cranks 41, are pivotally fastened to a lever 5| journalled in the center of the door Movement of the shaft 5| is controlled by a knob 59 on the outside of the door I I. This provides a convenient means for varying the exposure of the copy as, when the knob 99 is turned clockwise, the arms 49 cause the levers 41 to raise the cover 44 and increase the exposure of the aperture I9. Then to decrease the exposure, the knob 59 is turned counterclockwise and the cover 44 is lowered. The D and U arrows, shown in Figure 3, signify the movement of the cover 44 caused by turning the knob 50. As the cover 44 remains in any position in which it is placed, the copy can be exposed a line at a time if desired. 'I'he movement of the cover 44 also allows alignment of the exposed part of the aperture I9 with a line of the copy and dispenses with the necessity of adjusting the copy in the copy holder C.

If the transcriber ilnds it necessaryto read lines of copy on either side of the line which is exposed, or to estimate his relative position in the copy, the cover 44 and the door II can be raised as a unit by pulling outwardly and upwardly on a knob 53 on the door II (as shown in Figure 4). This swings 'the door on its hinge i3 and exposes nearly all ofthe copy in the copy holder C.

An open top reflector 59v is mounted on the casing I parallel to and just beneath the aperture 22 and is provided with an elongated electric lamp 51 positioned therein. As diagrammatically seen in Figure 2, leads 59 are connected to any convenient source of current supply and have a switch 58 which controls the supply of electrical energy going to the lamp 51.

The invention contemplates moving the copyin the copy holder C by remote control and one method of producing this result is by an electromagnet assembly shown in Figures 5 and 6.

An electro-magnet 92 is connected in parallel'A with the lamp 51, as shown in Figure 2. .It is mounted in back of the copy holder C by a bracket 9| which is secured to the bottom of the casing I0 by any convenient means, such as by a bracket 99.- A nat bar 93 is pivotally mounted at its center by a bolt 94 to a U bracket support 66 so that one end of the bari93 is in juxtaposi-, tion to the core of the electro-magnet 92. The support 99 is mounted on a; pin |54a which serves as a fulcrum for the assembled unit.

'When the electro-magnet 92 is energized, it pulls the adjacent end of the bar 93 against the end o! the magnetic core, due to the movable mounting of the bar 99., The amount of movementor the bar 49 is controlled by a bracket 9| which is rigidly mounted on the bar 93. The bracket 99 has an arm extending perpendicular to the bar 93 carrying a screw 99 with a lock nut 19 on it. The screw 99 isl adapted to bear upon the support 91 when the end of the bar 93 is moved away from the electro-magnet 92. It will be seen that if the position of the screw 99 in the bracket 99 is varied, it correspondingly varies the distance traversed by the end of the bar 99 away from the electro-magnet 92 before the screw 99 prevents further movement by bearing upon the support 91.

The end of the vbar 93 on the opposite side of the fuicrum 99 from the electro-magnet92 has an extension arm 12 attached atr'right angles to its longerside. The arm- 12 is pivotally secured as at 13 to a. split-headed upright 14, which is pivotally mounted on the side-wall 24 by a screw pin 18. An adjusting screw 19 on the split-head of the upright 14 can be tightened so that suiiicient friction is produced between the upright 14 and the screw 18, on which it swings, to prevent gravity from moving the upright 14.

A lever arm 15, provided with a pawl, is pivotally mounted at 19 on the free end of the upright 14. A spring 99 holds the pawl of the arm 15 in contact with a ratchet-wheel 11 mounted on the shaft 21 so that a forward movement of the arm 15 rotates the ratchet-wheel l1. The arm 15 has a cylinder 8| vwhich may be rotatable and which extends perpendicular to the arm 15 at its free end. The cylinder 9| strikes a nxed deector 82 when the arm 15 moves too i'ar forward and disengages the pawl from the ratchetwheel 11. A spring-guide 83, normally xed to the upright 14, keeps the arm 15 in alignment with the ratch-Wheel 11. Y

An arm 9| is pivotally mounted above and in vertical alignment with the ratchet-wheel l1 by a screw 92. 'I'he screw 92 engages with the sidewall 24 and acts as a fulcrum for the arm 9|. The arm 9| has a. roller 99 at one end and a spring 94 is connected to the other end in such a manner that the spring forces the roller 93 to constantly bear on the wheel 11 and prevent unactuated movement of the wheel 11.

When the electro-magnet 92 is energized it pulls the adjacent end vci' the bar 93 to it and, due to the fulcrum action oi the bracket t9 the other end of Vthe bar 93 is forced in the opposite direction, or towards the copy holder C. The extension arm 12 transmits this movement of the end of the bar 93 to the upright 14 which, in turn, is moved forward. Then, as the lever 15 is held substantially at right angles to the free end of the upright 14 and the pawl on lever 15 yenergized when the switch 5B is closed, an auxiliary switch |05 is placed in leads |94 which supply power to the electro-magnet 62. The switch IUS/is operated by an arm iBS connected to a lever |01, fulcrumed at |08 to a key |09 on its free end. The switch |05 is held open by a spring connected tothe arm |01 and closed only when the key |09 is depressed, so that when the key |09 is released, the spring ||0 again opens the switch |05. The switch and assembly is shown as being mounted on an ordinary typewriter T, but it could easily be placed at any remote position as for example on the deck D or other` suitable place.

This provides one method of controlling the ard spacer arm 95 is provided as a more convenient method for obtaining a standard amount of movement of the roll 26 by energizing the electro-magnet 62 once. The arm 95 is pivotally mounted on the side-wall 24 at 96 which is behind the ratchet-Wheel 11. The arm 95 can be moved so that the cylinder 8| of the arm 15 strikes and rides over the lower end of arm 95 when it is being pulled back for its next movev ment. 'I'he movement of the arm 95 is controlled by a spacer hook arm 91 which has three recesses in its top near one end. The arm 91 also uses the screw 92 as a fulcrum and has a spring 98 which forces the arm 91 against -a pin 99 in the arm'95 so that the pin 99 is always in one of the recesses in the arm 91. The arm.95 is moved by a knob |00 which projects out from the casing I0 at the end adjacent the side-wall 24.

When the knob |00 is in its lowest position,

' as shown in Figure 3, the pin 99 is in the recess nearest the end of the arm 91. This puts thefree end of the arm 95 in such a position that the cylinder 8| can move back the distance of the pitch of two ratchet-teeth before striking the arm 95. Then the pawl of the arm 15 rotates `the wheel 11 forward, the pitch of two teeth by one forward movement and thereby gives a double spacing movement to the roll 26. If single spacing is required, the knob |00 is moved up so Athat the pin 99 is inthe middle recess of the arm 91.. This moves the free end of the arm 95 forward so that it only allows the arm 15 to move back the pitch of one ratchet-tooth before the cylinder 8| hits the arm 95. the pawl from engagement with the ratchetwheel 11, the knob |00 is moved to its uppermost position, which puts the pin 99 in the recessnearest the fulcrum 92 of the arm 91. Now the free end of the arm 95 bears more or less downwardly on the cylinder 8| and forces the' arm 15 down by stretching the spring 80 so that the pawl is disengaged from the ratchet. When this isdone, the roll 26 can be moved in a counterclockwise direction and therebyeffect a second exposure of the copy paper on it. The numerals 1 and 2, shown on the casing I0 in Figure 3, represent theposition of the knob |00 required to secure single or double space movement of the roll 26.

Anotherfeature of the invention is a lever ||1 rigidly connected to the bar 63 and provided with a pawl on its free end. Thepawl on the lever ||1 engages with a ratchet ||9 of a counter |20 and it, as well as the arm ||1, is moved when the electro-magnet 62 is energized. This movement turns the counter |20 as the arm ||1 is Then, to remove engaged with the ratchet 9 connected to it. This provides means for counting the'number of lines of copy transcribed as the copy holder C is designed to rotate a new line of copy into view each time the .bar 63 `is moved byA energizing Vthe electro-magnet 62 and such movement` can be taken as a unit in reading the counter |20.

A cover |2| is provided to enclose the operating mechanism so as to improve the appearance of the copy holder C and protect the mechanism from dirt.
